Referring now more particularly to the accompanying drawings whereinlike and corresponding parts are designated by similar referencecharacters, A indicates a drywall having front and back wallboardsupported by upright studs B and C and horizontal studs D providing adoor opening in the drywall. Horizontal sill studs E and F are mountedon the floor and have the lower ends of studs B and C, respectively,mounted thereon. This is a conventional construction of a stud openingin a drywall.

Hinge jamb l, strike jamb 2, and frame head 3 are the basic elements ofthe present frame. Hinge jamb l and strike jamb 2 are essentiallysimilar when they have a double rabbett profile with equal rabbetts,except for attached hardware and openings, and therefore, only one suchjamb is described. That is, the hinge jamb and the strike jamb each havea center portion 4, a pair of side walls 5 and 6 extending normal to andfrom the edges of said center portion providing a center channel orstop, a pair of front walls 7 and 11 each extending normal to and froman edge of said side walls 5 and 6 respectively, a pair of end walls 8and 12 each extending normal to and from an edge of said front walls 7and 11' respectively providing a second channel, a pair of rear walls 9and 13 extending normal to and from an edge of said end walls 8 and 12respectively, and a pair of inner walls 10 and 14 extending normal toand from an edge of said rear walls 9 and 13, respectively. Thus, innerwalls 10 and 14 are parallel to and spaced from end walls 8 and 12,respectively. Said center portion 4 and walls 5 to 14 are each flat,that is, they are each straight in their lateral and longitudinaldirections.

Hinge jamb 1 only has a plurality of rectangular recesses 15 in frontwall 7 thereof, each contiguous with a short recess in end wall 8alongside each recess 15. A plurality of plates 16 each have offset earsl7 and 18 and screw holes 19. Ears l7 and 18 of each plate 16 is affixedto the rear of wall 7 by spot welding or the like on opposite sides ofeach recess 15 so that each plate 16 extends across one of saidrecesses, but is spaced above wall 7. Thus, one leaf of a hinge (notshown) may be placed in each recess 15 and affixed by screws to theplate 16 thereacross with the other leaf of the hinge affixed in theknown manner to a door (not shown).

Each jamb 1 or 2 has a pair of sill anchors 20 as best shown in FIG. 6.Each sill anchor 20 has screw holes 21 for the passage of screws ornails therethrough into sill studs E and F. Also, each sill anchor has abent medial portion 22 and an inner end portion 23 positioned on thelower end portion of an end wall 8 or 12 and affixed thereto by spotwelding 24 or the like.

The upper end portion 25 of each end wall 8 or- 12 extends on a slant,for example, on a 45 angle, from a side of its corresponding front wall7 or III to the upper edge of its corresponding rear walls 9 and 13.That is, the upper edge of center portion 4 and walls 5, 6, 7, and 11are straight across and perpendicular to the longitudinal direction ofthe jamb and each upper end portion 25 starts from walls 7 or 11 belowsaid upper edge of said walls as shown in FIG. 6 and extends to theupper edges of walls 9 and 13 while the upper edge of walls 9, 10, 13and 14 are straight across and perpendicular to the longitudinaldirection of the jamb.

A pair of slots 26 and 27 are provided in front walls 7 and 11 justabove a line extending from the lower ends of the upper end portions 25.

Each jamb center portion 4 has a concavo-convex inwardly extendingcountersink 28 in the portion thereof near its upper end portion 25.Each countersink 28 has an annular center opening 28a with radial slits28b. An adjusting screw 29 is inserted through each opening 28a and thesections of the countersink on each side of the slits 28b arepermanently crimped into the grooved neck of the adjusting screw 29 sothat said screw cannot be removed but its head is in the countersink onthe exterior of the jamb for being turned by a screw driver as required.

Also, each jamb has a drywall compression anchor 30 or 30' which have acenter opening 30a above which is mounted a weldnut 29b with screws 29extending through opening 30a and in threaded engagement with weldnut29b. Anchors 30 and 30' have perpendicular side walls 31 and 33 withears 32 and 34 extending laterally each from its corresponding side wall31 or 33. Ear 32 of anchor 30' has a concavo-convex central portion 32awhich widens at 32b into wall 31. Similarly, ear 34 of anchor 30' has aconcave-convex central portion 34a which widens at 34b into wall 33.

Strike jamb 2 has a pair of keepers 35 mounted on the inner face offront wall 11 at a position on said jamb for a female portion of a lock(not shown). Keepers 35 each have an end portion 36 attached by spotwelding or the like to front wall 11, a slanting medial portion 37 andan opposite end portion 38 parallel to, but spaced from wall 11 andhaving a threaded opening 39 with end portions 38 extending towards, butspaced apart from one another.

A flat bottom 40 of a housing has perpendicularly extending end walls 41and 43 with cars 42 and 44 each extending normal to and from itscorresponding end wall 41 or 43. Ears 42 and 44 can be slideablyinserted beneath end portions 38 of said keepers as shown in FIG. 8 andhave openings corresponding to openings 39. The jamb wall 11 has arecess 45 opening beneath the tips of end portions 38 of said keepersand said housing bottom 40 and a recess 46 in wall 12 contiguous withrecess 45. Screws 39a extend through openings in cars 42 and 44 and arein threaded engagement with openings 39. Screws 39a also are used toretain the female lock portion in said housing.

The frame head 3 has a center portion 47, side walls 48 and 49 extendingnormal to and from the opposite edges of center portion 47 providing achannel, front walls 50 and 55 extending normal to and from side walls48 and 49, respectively, end walls 51 and 56 extending normal to andfrom front walls 50 and 55, respectively, rear walls 52 and 57 extendingnormal to and from end walls 51 and 56, respectively, and inner walls 53and 58 parallel to, but spaced from end walls 51 and 56, respectively.Said center portion 47 and walls 48 to 56 are flat, that is, straight inboth their lateral and longitudinal directions.

Also, center portion 47 and walls 50 and 55 correspond to and are of thesame width as center portion 4 and front walls 7 and 1 1 respectively ofsaid jambs.

End walls 51 and 56 each have opposite end edges 59 each of whichslants, for example on a 45 angle, from an end of walls 50 and Soutwardly to an end of rear walls 52 and 57. Inner walls 53 and 58 haveopposite end edges spaced inwardly from the corresponding end edges ofrear walls 52 and 57, a distance equal to the width of jamb walls or 14.The opposite ends of center portion 47 and side walls 48 and 49 arestraight across and are spaced inwardly from the corresponding ends offront walls 50 and 55 a distance equal to the width ofjamb side walls 5and 6.

Front wall 50 has a pair of tongues 60 each extending longitudinallyfrom an opposite end of said front wall. Similarly, front wall 55 has apair of tongues 61 each extending longitudinally from an opposite end ofsaid front wall 55.

The jambs 1 and 2 and head 3 as above described have double rabbettprofiles which may be of equal or unequal rabbetts. That is, the jambsand head have similar cross-sectionalconfiguration and the front walls 7and 50 may be the same width as 11 and 55 may be wider than walls 7 and50. Also, said jambs and head may each have a cross-sectionalconfiguration as shown in FIG. 10 to have a single rabbett profile. Thatis, each jamb and the head may have a front wall 4a, single side wall 6ajoining front wall 11a to front wall 40 and end walls 8a and with wall8a narrower than wall 12a. Wall 8a has the same double return of wall12a and thus, as in the jambs and head of FIG. 6.

Jambs l and 2 and head 3 are produced separately, but can be stored,sold, and shipped as a unit, but without being connected together. Whenit is desired to erect the frame a suitable stud opening is provided indrywall A as indicated in FIG. 1. Hinge jamb 1 is then slipped over thedrywall with jamb inner walls 10 and 14 having the wallboardtherebetween and stud C extending along the inner side of front walls 7and 1 1.

Head 3 is then slipped over the drywall with the wallboard between andagainst inner walls 53 and 58 and stud D on the inner side of frontfaces 50 and 55. At this time tongues 60 and 61 at the left end of thehead in FIG. 1 are inserted through the slots 26 and 27 respectively ofthe hinge jamb until head edge 59 at the left of the head matches withhinge jamb edge 25.

Strike jamb 2 is then slipped over drywall A with the wallboard betweenand against inner walls 10 and 14 of the strike jamb, stud B positionedon the inner side of the front walls 7 and 11 of the strike jamb andtongues 60 and 61 at the right end of the head of FIG. I insertedthrough the slots 26 and 27 respectively of the strike jamb and theupper edges 25 of side walls 8 and 12 of the strike jamb matching withthe right hand edges 59 of the head side walls 51 and 56. Walls 4, 5,and 6 of the hinge jamb l are then in the recess provided by the leftend of center portion 47 with front walls 50 and 55, and similarly,walls 4, 5, and 6 of the strike jamb 2 are in the recess provided by theright end of center portion 47 with front walls 50 and 55.

Thereupon each screw 29 is turned until its anchor 30 or 30' abuts itsstud B or C. Then both screws are turned until the frame is wedgedsecurely between the studs. Hinge jamb 1 is plumbed and its sill anchors20 fastened by screws to sill stud F and then the sill anchors 20 of thestrike jamb are similarly fastened to sill stud E. The frame is thenready for the attachment of a door and hardware as desired.

A modified form of a sill anchor is shown in FIGS. 13 and 14 andconsists ofa flat plate 20a having a bent end portion 20b giving thesill anchor an L-shaped configuration. Plate 20a has a pushed out tongue200 which extends parallel to, but is spaced from plate 20a thethickness of inner wall 10 or 14. As shown in FIG. 14, tongue 20c ispositioned behind inner wall 10 or 14 with plate 20a on the exteriorthereof and the bent end portion 20b pushed against front wall 7 or 1 1.Thus, the sill anchor can be quickly assembled to the door frame withoutthe use of tools and plate 200 has openings 21a for the passage ofscrews or nails in the sill in the same manner as sill anchor 20.
